User-Agent: Mutt/1.5.18 (2008-05-17) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi, Just had a strange situation with the above upgrade. It was done on an old server that used the serverworks ide driver. The IDE hw config under 2.6.23.16 was: hda: HD hdb: CDROM hdc: empty hdd: HD After upgrade, using either IDE or libata the config changed to: hda: HD hdb: CDROM hdc: empty hdd: empty The BIOS recognised the disk. I went through 3 disks and it wasn't until I made the second HD a master that it was recognised. So now I have a 2.6.32.9 server, using the IDE subsystem with the following config: hda: HD hdb: CDROM hdc: HD hdd: empty Otherwise it does not work. I had an outage window that I already blew so I was not able to do any more diagnosis than what it took to get the system up. If anyone wants the full config I'll send. Otherwise: IDE subsystem (no libata subsystem configured): CONFIG_HAVE_IDE=y CONFIG_IDE=y CONFIG_IDE_XFER_MODE=y CONFIG_IDE_ATAPI=y CONFIG_IDE_GD=y CONFIG_IDE_GD_ATA=y CONFIG_BLK_DEV_IDECD=y CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS=y CONFIG_BLK_DEV_IDEACPI=y CONFIG_IDE_PROC_FS=y CONFIG_BLK_DEV_IDEDMA_SFF=y CONFIG_BLK_DEV_IDEPCI=y CONFIG_IDEPCI_PCIBUS_ORDER=y CONFIG_BLK_DEV_IDEDMA_PCI=y CONFIG_BLK_DEV_IDEDMA=y CONFIG_LEDS_TRIGGER_IDE_DISK=y libata kernel (no IDE subsystem configured): CONFIG_ATA=y CONFIG_ATA_VERBOSE_ERROR=y CONFIG_ATA_ACPI=y CONFIG_SATA_PMP=y CONFIG_ATA_SFF=y CONFIG_PATA_SERVERWORKS=y -- "A search of his car uncovered pornography, a homemade sex aid, women's stockings and a Jack Russell terrier." - http://www.news.com.au/story/0%2C27574%2C24675808-421%2C00.html
